I think those are the 703"s ? For some reason they dont look right to me, i dunno. BUt i bought this set for me JeeP and they work great with sooper performance. I lost 1 mpg though with this set, maybe i got a heaver bit more lead in me boot

They aren't the 703s. The 703s have the older Jetronic/Minitimer connector; the ones in the link have the USCAR connector. The 703s are also black.

I just switched my 703s out for 715s. Paid $18 for all six at the local yard and cleaned them on my home made rig.

They look like 789's. But ask the ebay seller.

Green are 789. I have those in my 5.9. They should come with an adapter harness or you can buy your own.

i know this is a bump, and im not gonna read through 40 pages to see if anyones tried it and it just hasnt been updated, but i just tried 715s from a 05 crown vic PI in my 95 4.0, and it ran like ***. wayy too rich. im 99% sure they dont leak, because theyre brand new.

Sometimes the injectors, regardless of engine and type of injector, are hit or miss for people.

That makes sense...715s flow way higher than 703s. I would return them/sell them for some 703s

I have a 96 ZJ 4.0 and swapped from the 778 to the 710 injectors. I am having a problem with getting a good seal between the fuel injectors and the fuel rail. the first time I did it, it seemed to work fine but after about 1000 miles they started leaking. what happened was the o rings are getting pinched because the injectors and fuel rail are meeting at a strange angle. any tips or work arounds for this so it doesn't happen again next time?

703 x 789

First of all, thanks for this great thread. I got hooked reading till the end.
Now I want to do the injectors upgrade in my 98 ZJ 5.9. I have headers, hiflow cat, k&n cai, accel coil, cables and plugs, mopar rotor and cap, msd 6a box. No major work, just add on for the 155k miles engine.
I already did some contacts with few ebay sellers and I have a deal on hand for even 703 or 789+Adaptors. But I have a doubt: should I go 703 or 789??
So, which one I should have a better compatibility , mileage and performace??
Little lost here!
Thanks

You all might have noticed I redid the original post so that it's a little better organized and easier to understand, and removing some useless information. Hope you all like it!
